通过运用SHTTⅡ型熔化结晶温度测试仪构建了TTT曲线,计算出不同CaF2下保护渣脱玻化活化能;再通过X射线衍射仪并结合JADE软件计算出结晶率和分析结晶矿相;最后利用金相显微镜,观察多种回温处理下不同CaF2含量的保护渣渣膜的表面形貌,探究CaF2对保护渣脱玻化的影响.试验结果表明:随着CaF2含量增加保护渣脱玻化的温度和活化能不断降低,渣膜表面粗糙度增大;随着玻璃体渣膜处理温度的升高,保护渣析出矿相种类单一化.
TTT curve was constructed using SHTT Ⅱ melting and crystallization temperature measuring instrument,then the mold flux devitrification activation energy was calculated at different levels of CaF2.To calculate the rate of crystallization and analysis crystalline phase,X-ray diddractometer combining with the JADE software are utilized.Various surface morphology of slag film protection with different CaF2 content under the different temperature treatment was observed under the metallographic microscope,exploring the impact of CaF2 on the devitrification of slag.It is found out that the temperature and activation energy of initial devitrified phenomenon decreases and the roughness on the surface of flux film increases with the CaF2 content increasing.The mineral species tend to be single with treating temperature of glassy flux film increasing.
